ABSTRACT
Introduction: Lateral neck dissection (LND) in thyroid cancer has traditionally been performed by a transcervical technique with a large collar incision. With the rise of endoscopic, video-assisted, and robotic techniques for thyroidectomy, minimally invasive LND is now being performed more frequently, with better cosmetic outcomes. Methods: The purpose of this paper is to review the different minimally invasive and remote access techniques for LND in thyroid cancer. A comprehensive literature review was performed using PubMed and Google Scholar search terms "thyroid cancer" and "lateral neck dissection" and "endoscopy OR robot OR endoscopic OR video-assisted". Results: There are multiple surgical options now available within each subset of endoscopic, video-assisted, and robotic LND. The approach dictates the extent of the LND but almost all techniques access levels II-IV, with variability on levels I and V. This review provides an overview of the indications, contraindications, surgical and oncologic outcomes for each technique. Discussion: Though data remains limited, endoscopic and robotic techniques for LND are safe, with improved cosmetic results and comparable oncologic and surgical outcomes. Similar to patient selection in minimally invasive thyroidectomy, it is important to consider the extent of the LND and select appropriate surgical candidates.
ABSTRACT
INTRODUCTION: Adrenal hemorrhage (AH) can occur due to multiple etiologies with variable radiographic appearance, often indistinguishable from underlying adrenal neoplasms. There is a lack of AH literature and evidence-based guidelines. Our study aimed to understand the prevalence and etiology of AH, follow-up, and incidence of underlying neoplasm. METHODS: An institutional database was queried from January 2006 to October 2021 for patients with AH on imaging, excluding patients with known malignancies, adrenal masses, or prior adrenal surgery. Demographics, medical history, hematoma size, laterality, biochemical evaluation, intervention, and additional imaging were reviewed. RESULTS: Of 490,301 imaging reports queried, 530 (0.11%) with AH met inclusion criteria. Most imaging (n = 485, 91.5%) was performed during trauma evaluation. Two patients underwent dedicated intervention at presentation. Interval imaging was performed in 114 (21.5%) patients at a median of 2.6 (interquartile range 0.99-13.4) mo, with resolution (n = 84, 73.7%) or decreased size of AH (n = 21, 18.4%) in most patients. Only 10 patients (1.9%) saw an outpatient provider in our system to address AH or evaluate for underlying mass, and 9 (1.7%) underwent biochemical screening. Thirteen patients (11% of 118 patients with any follow-up) had evidence of an adrenal mass, confirmed on serial imaging (n = 10) or adrenalectomy (n = 3). Scans performed for nontrauma indications were significantly more likely to have an underlying mass (n = 6/26 [23.1%]) than those performed for trauma evaluation (n = 7/92 [7.6%], P = 0.04). CONCLUSIONS: AH is a rare finding associated with an increased rate of underlying adrenal mass, particularly when unrelated to trauma. Most AH resolves spontaneously without intervention. Follow-up imaging at 6 mo can help distinguish mass-associated AH from simple hemorrhage.

BACKGROUND: The association between surgical volume and patient outcome is well established, with higher case volume associated with a lower risk of complications. We hypothesized that the geographic distribution of endocrine/head and neck surgeons with an endocrine focus in the United States and Puerto Rico may limit access to many potential patients, particularly in rural areas. METHODS: We used web-based directories from the American Association of Endocrine Surgeons, American Head and Neck Society, and the American Academy of Otolaryngology-Head and Neck Surgery to identify endocrine surgery specialists in the United States and Puerto Rico. Using geographic coordinates and OpenStreetMap and Valhalla software, we calculated the areas within a 60-, 90-, or 120-minute driving distance from specialist offices. We used 2020 U.S. Census Data to calculate census tract populations inside or outside the accessible areas. RESULTS: Excluding duplicate providers across organizations, we geocoded 603 specialist addresses in the United States and Puerto. We found that 23.76% (78.3 million) of Americans do not have access to a society-affiliated endocrine/head and neck surgeon with an endocrine focus within a 60-minute drive, 14.37% (47.4 million) within a 90-minute drive, and 8.38% (27.6 million) within a 120-minute drive. We observed that the areas of coverage are primarily focused on metropolitan areas. CONCLUSION: Nearly one-third of Americans do not have access to a society-affiliated endocrine/head and neck surgeon with an endocrine focus within a 1-hour drive, highlighting a concerning geographic barrier to care. Further work is needed to facilitate patient access and mitigate disparities in quality care.

BACKGROUND: The transgender/gender nonconforming (TGNC) population is growing exponentially, but surgeon education has not advanced accordingly. Our objective was to assess department-wide understanding, awareness, and comfort in treating TGNC patients and identify specific gaps in education and training needs. METHODS: A survey covering 4 domains (personal perceptions; prior healthcare training/experience; comfort providing care; barriers to access) regarding TGNC patients was distributed to surgery faculty and trainees at an urban referral center. The survey contained 24 5-point Likert scale and 6 multiple choice demographic items. There was a 4-week response window. Descriptive statistics assessed the relative frequency of responses. The main outcome measures were the gaps and variation in each domain. RESULTS: There was a 47.59% (89/187) response rate and split evenly between trainees and attendings. Over half (51.21%, nâ¯=â¯44) reported formal TGNC training, mainly in medical school (27.5%, nâ¯=â¯22). Most knew (72.41%, nâ¯=â¯63) and had experience caring for TGNC patients (74.71%, nâ¯=â¯65). There was disparity understanding general concepts, with disagreement on definitions (8.99%, nâ¯=â¯8) and gender choice (14%, nâ¯=â¯12). Most reported comfort with communication, and could initiate conversations on pronouns (75.6%, nâ¯=â¯65) and gender identity (71.7%, nâ¯=â¯65). Over 40% could not complete a comprehensive history and admitted discomfort performing physical exams. Despite this, 88.51% (nâ¯=â¯77) felt they could provide an adequate level of care. Most respondents recognized unique TGNC health risks (91.86%, nâ¯=â¯79) and access barriers (82.76%, nâ¯=â¯72), including providers' lack of TGNC cultural competency (82.76%, nâ¯=â¯72). CONCLUSION: Disparities existed across all domains needed for inclusive TGNC surgical care. Respondents were aware of unique health needs and barriers to access. Provider self-perceived experience did not match the knowledge and skill required to provide optimal care for TGNC patients.

Early surgical intervention decreases mortality in necrotizing soft tissue infections (NSTIs). Yet, a subset of patients will not have NSTIs (non-NSTIs) at the time of exploration. We hypothesized that NSTI and non-NSTI patients had similar causative organisms and that intraoperative wound cultures could help guide management. Culture results and outcomes were compared for all patients undergoing surgery for suspected NSTIs over a seven-year-period. Of 295 patients, 240 (81.4%) had NSTIs. Of the 55 non-NSTI patients (18.6%), 50 had cellulitis and 5 had abscesses. NSTI and non-NSTI patients had similar rates of bacteremia (20.4% vs 17.6%, P = 0.66), septic shock (15.9% vs 12.7%, P = 0.68), and mortality (10.4% vs 7.2%, P = 0.62). Wound cultures were collected more often in NSTI patients (229/240, 95.4%) than in non-NSTI patients (42/55, 76.4%, P < 0.01). Non-NSTI patients had positive deep wound cultures more than half of the time (23/42, 54.8%). The microbiologic profile was similar between groups, with Methicillin Resistant Staphylococcus aureus and Group A Streptococcus occurring with the same frequency. We advocate for deep wound cultures in all patients being evaluated operatively for NSTIs even if the exploration is considered negative because these patients have similar clinical characteristics and virulent microbiology, and culture results can help guide antimicrobial therapy.

BACKGROUND: Necrotizing soft tissue infections (NSTI) are aggressive infections associated with significant morbidity and mortality. Despite multiple predictive models for the identification of NSTI, a subset of patients will not have an NSTI at the time of surgical exploration. We hypothesized there is a subset of patients without NSTI who are clinically indistinguishable from those with NSTI. We aimed to characterize the differences between NSTI and non-NSTI patients and describe a negative exploration rate for this disease process. METHODS: We conducted a retrospective review of adult patients undergoing surgical exploration for suspected NSTI at our county-funded, academic-affiliated medical center between 2008 and 2015. Patients were identified as having NSTI or not (non-NSTI) based on surgical findings at the initial operation. Pathology reports were reviewed to confirm diagnosis. The NSTI and non-NSTI patients were compared using χ2 test, Fisher's exact test, and Wilcoxon rank-sum test as appropriate. A p value <0.05 was considered significant. RESULTS: Of 295 patients undergoing operation for suspected NSTI, 232 (79%) were diagnosed with NSTI at the initial operation and 63 (21%) were not. Of these 63 patients, 5 (7.9%) had an abscess and 58 (92%) had cellulitis resulting in a total of 237 patients (80%) with a surgical disease process. Patients with NSTI had higher white cell counts (18.5 vs. 14.9 k/mm3, p=0.02) and glucose levels (244 vs. 114 mg/dL, p<0.0001), but lower sodium values (130 vs. 134 mmol/L, p≤0.0001) and less violaceous skin changes (9.2% vs. 23.8%, p=0.004). Eight patients (14%) initially diagnosed with cellulitis had an NSTI diagnosed on return to the operating room for failure to improve. CONCLUSIONS: Clinical differences between NSTI and non-NSTI patients are subtle. We found a 20% negative exploration rate for suspected NSTI. Close postoperative attention to this cohort is warranted as a small subset may progress. LEVEL OF EVIDENCE: Retrospective cohort study, level III.
ABSTRACT
Developmental transitions are often triggered by a neuroendocrine axis and can be contingent upon multiple organs achieving sufficient growth and maturation. How the neurodendocrine axis senses the size and maturity of peripheral organs is not known. In Drosophila larvae, metamorphosis is triggered by a sharp increase in the level of the steroid hormone ecdysone, secreted by the prothoracic gland (PG). Here, we show that the BMP2/4 ortholog Dpp can function as a systemic signal to regulate developmental timing. Dpp from peripheral tissues, mostly imaginal discs, can reach the PG and inhibit ecdysone biosynthesis. As the discs grow, reduced Dpp signaling in the PG is observed, consistent with the possibility that Dpp functions in a checkpoint mechanism that prevents metamorphosis when growth is insufficient. Indeed, upon starvation early in the third larval instar, reducing Dpp signaling in the PG abrogates the critical-weight checkpoint which normally prevents pupariation under these conditions. We suggest that increased local trapping of morphogen within tissues as they grow would reduce circulating levels and hence provide a systemic readout of their growth status.
